Happy Saturday Huskies!

The atmosphere and the ocean teamed up and served a cold front of cool wet marine air to the Pacific Northwest last night. The pitter-patter of rain started around 9:00 P.M. in Seattle and continued through the night. Nearly an inch of rain has fallen at the UW Seattle campus and over an inch-and-a-half has accumulated in the Olympic and Cascade Mountains. Our lush temperate rainforests are soaking in the nutrients and the tree frogs are croaking in happiness! True classic “Cascadian Weather” is back!

By late morning the cold front has moved east out of the region, but some precipitation will linger. Blustery weather and scattered showers will persist throughout the day. With all the rain from last night’s front, it might be a little muddy to visit a pumpkin patch. However, you might catch a few sunbreaks this afternoon with the unstable post-front air. A convergence zone should develop in King and Snohomish County. If you live a few miles north of campus, you could see some active showers. There is even a chance of afternoon thunderstorms.

With all the clouds and precipitation, expect a miniscule diurnal range of temperatures. After last night’s low of 56, temperatures are expected to only warm by five or six degrees, with a high temperature in the lower 60s. Tonight’s low show dip into the lower 50s.

Another system of rain will reach Seattle mid-day tomorrow with precipitation totals around a half inch of additional rain likely. Snow is expected at elevations of 5,000 feet and up and gusty winds up to 40 mph are possible in western Washington tomorrow. If you are traveling this weekend, keep an eye on the forecast in your region.

Enjoy your weekend and the “Cascadian” weather!
